The invention provides an automobile connecting plate stamping die. The die comprises a lower die holder fixedly arranged and an upper die holder located over the lower die holder. A male die body isarranged in the middle of the upper die holder. A female die body matched with the male die body is arranged on the lower die holder. Two opposite push-pull units are arranged on the two side walls ofthe upper die holder correspondingly. Each push-pull unit comprises a transverse pressing rod connected to the side wall of the upper die holder, a connecting oblique rod movably connected with the end of the transverse pressing rod, and a transverse push rod movably connected with the end of the connecting oblique rod. Moving grooves matched with the transverse push rods are further formed in the lower die holder. Moving blocks are arranged in the moving grooves correspondingly and pushed by the transverse push rods to move in the moving grooves correspondingly. According to the automobile connecting plate stamping die provided by the invention, by arranging the push-pull units, in the lower die holder moving process, the push-pull units are driven to extrude the moving blocks so as to clamp and stabilize a connecting plate, the stamping die of he connecting plate is guaranteed, and the automobile connecting plate stamping die is simple in structure and high in work efficiency.
